A liquid composition having a moth-repelling effect

Abstract: The moth-repelling composition of the invention utilizes a clove-tree leaf essential oil coming from Madagascar in association with citronella oil from Java, Patchouly 35501, lavender extract from Marseille, lavender extract from Apt, and lavender extract from Vaucluse, as well as fixolide and benzyl salicylate as preservative agents and various other components.

Description: This invention relates to a liquid composition having a moth-repelling effect, wherein the composition is based on natural components having no harmful influence on human body and whose moth-repelling effect is more extended in time. In particular, the composition according to the invention makes use of the following substances as its active components: essential oil of Clove-tree leaf from Madagascar, citronella oil from Java, Patchouly 35501, lavender extract from Marseille, lavender extract from Apt lavender extract from Vaucluse; as well as benzyl salicylate and fixolide, these latter acting as preservatives for the product to keep effectiveness of the product over a longer period of time. The composition according to the invention falls within the class of products having a repelling effect on moths, that is products capable of giving off vapours over a certain period of time which are moth-repellent due to their being highly irritant to these insects. These products can act, as the case may be, by evaporation or sublimation of the substances composing the moth-repelling preparation, which in turn, can be from either a natural or synthetic source. In the case of synthetic products, the vapours they give off are usually toxic to moths which generally die when in a space full of the vapours, for example, inside a wardrobe. However, this toxicity also affects, though to a very lower extent, human beings who inhale said vapours, for example, when staying in a room where the wardrobe is placed. Natural compositions with low or no toxicity are also known. Examples of products of this type presently in use are citronella, lavender, or clove oil used either individually or in combination. These compositions have, however, not found widespread acceptance hitherto in that these natural products have in general relatively poor and/or very short effectiveness, so that it is necessary to use the product in more concentrated form and/or to replace it frequently which is not cost effective. In view of the above, a need has been felt in this connection for a product which has good moth-repelling property while maintaining its effectiveness over longer periods of time , and which is non-toxic to the human body. These objectives are attained with the composition according to this invention which is the result of many thorough experiments by the applicant and whose features are as defined in the characterizing parts of the annexed claims. The moth-repelling composition of the invention utilizes a clove-tree leaf essential oil coming from Madagascar in association with citronella oil from Java, Patchouly oil 35501, lavender extract from Marseille, lavender extract from Apt, and lavender extract from Vaucluse, as well as fixolide and benzyl salicylate as preservative agents and various other components to be described later. By the use of the components referred to above the inventor has been able to work out a composition which is much more powerful in efficency than similar products of the prior art and whose effectiveness can last over a period of 1 to 3 months, depending on physical and thermal conditions in a room, a result which can be considered as satisfactory. The moth-repelling compound of the invention has the composition as follows: 1) 4 to 6 parts per thousand (p.p.thousand, in the following) by weight, preferably 5 p.p.thousand by weight Synthetic Linalol (3,7-Dimethyl-1.6-ocatadien-3-ol), 2) 12 to 18 p.p.thousand by weight, preferably 15 p.p.thousand by weight Synthetic Linalyl acetate (Linalyl acetate), 3) 20 to 30 p.p.thousand by weight, preferably 25 p.p.thousand by weight Lavender oil absolute Ether (a lavender extract from Marseille - France). 4) 50 to 70 p.p.thousand by weight, preferbaly 60 p.p.thousand by weight Lavender oil HT E 2294 (a lavender oil from Apt - France), 5) 50 to 70 p.p.thousand by weight, preferably 60 p.p.thousand by weight Lavender Oil Maillette 7-59 (a lavender oil from Vaucluse - France), 6) 40 to 60 p.p.thousand by weight and preferably 50 p.p.thousand by weight Fixolide (7 - Acetyl - 1,1,3,4,4,6, - hesamethyl - tetralin), 7) 40 to 60 p.p.thousand by weight and preferably 50 p.p.thousand by weight Benzylsalicylate LG (Benzyl 2 - hydroxybenzoate benzyl salicylate), 8) 90 to 110 p.p.thousand by weight and preferably 100 p.p.thousand by weight Resinoid Benzoe Siam 50% (purified Benzoe-plant resin, an oil with a proper aroma coming from Thailand), 9) 90 to 110 p.p.thousand by weight and preferably 100 p.p.thousand by weight Cologne Water S. 1243 (a product available from Essencie AG, Winterthur (CH)), 10) 90 to 110 p.p.thousand by weight and preferably 100 p.p.thousand by weight Orphea E 226 (a product available from Essencie AG, Winterthur CH)), 11) 90 to 110 p.p.thousand by weight and preferably 100 p.p.thousand by weight Bouquet E 163 (a light yellow-to-brown-coloured essential oil based on Methylionon, Hydroxycitronellal), (a product sold by Essencie AG, Winterthur (CH)). 12) 250 to 300 p.p.thousand by weight and preferably 280 p.p.thousand by weight Patchouly 35501 Esrolko 9355010 (a red-to-brown-coloured essence coming from Indonesia based on Patchouly oil Indonesia, Nopylacetate, a product available from Givaudan SA, Genf (CH)). 13) 30 to 40 p.p.thousand by weight and preferably 35 p.p.thousand by weight Orphea 11445 Esrolko 9114450 (a sweet-smelling orange-coloured essential oil based on Hydroxycitronellal, Citronella oil, a product available from Givaudan SA, Genf (CH)), 14) 5 to 15 p.p.thousand by weight and preferably 10 p.p.thousand by weight Citronella oil Java, 85/35% ph.

Products 1) and 2) are substances having a proper aroma which is repellent for insects. Compound 15), a clove-tree leaf essential oil from Madagascar, has shown to be determinant in keeping off moths from woollen clothes, while products 6) and 7), Fixolide and Salol, act to preserve the product so as to cause it to maintain its effectiveness for a longer time. The olfactory perception produced by the moth-repelling vapours is pleasant due to these vapours being sweet-smelling. According to a preferred embodiment of the invention, use is made of an absorbent paper as the mechanical support for the composition which is produced in liquid state, the absorbent paper being impregnated with the composition. However, many other types of supports may also be utilized as long as the support is of adeguate porosity and is workable in character so that support shapes most adapted for individual specific applications can be obtained. The single substances used have been referred to above with the names under which these substances are designated by their manufacturers and known by those skilled in the art. The thus obtained product has undergone many tests showing the product to have considerable effectiveness and be capable of exerting its activity over a sufficiently extended period of time ranging fro 1 to 3 months. This formulation may be completed, if necessary, by adding other compounds such as Pyrethrum, etc., to it.
